APPARATUS FOR SOLDERING CANS.

SPECIFICATION forming part of Letters Patent No. 717,896, dated January 6, 1903.

Application filed November 12, 1900. Serial No. 36,178. (No model.)

To all whom, it concern:

Be it known that L-FRANCIS P. MCCOLL, a citizen of the United States, residing in the borough of Brooklyn, city of New York, and State of New York, have invented certain new and useful Improvements in Apparatus for Soldering Cans, of which the following is a specification. i

The annexed drawings and the following description set forth in detail one mechanical form embodying the invention, said detailed construction being but one of various mechanical forms in which the principle of the invention may be used.

In the accompanying drawings, Figure l is a plan view of the holder, showing the yielding top or cover broken away in part. Fig. 2 is a bottom view of the holder. Fig. 3 represents a longitudinal section of the holder on line 3 3 of Fig. 1. Fig. 4 represents a transverse section of the holder on line 4 4 of Fig. 1. Fig. 5 is a diagrammatic view illus' trating the apparatus and method of using same.

The apparatus consists, essentially, of a holder Ct for the parts of the can or receptacle to be soldered together-that is, provided with a yielding cover or top I). Said cover is yieldingly'secured to the holder in any suitable manner, but preferably ismounted upon a stud or projection 0, provided upon. a bar d, that is hinged atf to the side or wall 9 of the holder. A spring interposed between the cover and the bar presses the cover yieldingly in engagement with the top of the holder or with the body portion of the can or receptacle contained therein. The guiderods h are provided upon the bar which project through the perforations 1), formed in the cover, and prevent same from rotating on the stud. Suitable means, such as a head or collarj, is formed on the inner end of this stud or projection to hold the cover against disengagement from the bar when same is raised and the cover is opened. A suitable catch k maybe provided that engages the end of the bar and holds the cover in its closed position. The wall or sides of the holder correspond in outline with the body of the can or receptacle to be soldered, so as to provide a firm support for the body portion 1 of the can or receptacle and prevent same from slipping while the top or bottom portion m of the can or receptacle is being soldered thereto. Preferably the upper part it of the wall is beveled slightly, so as to permit easy removal. of the receptacle, and the bottom 0 of the holder is also provided with openings 19 adjacent to the wall or sides and may be secured by any suitable means, as by lugs q. The wall of the holder is constructed so that the body portion of the can or receptacle will project slightly above same when the parts to be soldered are placed therein.

The bottom or top portion of the can or receptacle is first put in the holder, and then the body portion, having been dipped in solder in the usual manner, is placed therein. The holder is then closed, which brings the cover yieldingly in engagement with the body portion of the receptacle and presses same firmly but yieldingly against the bottom or top portion thereof. The cover is so mounted upon the hinged bar that the pressure from the spring is distributed equally around the entire periphery of the body portion. To complete the operation and insure a tight joint, the holder may be placed in an endless carrier 0 and the inclosed can or receptacle subjected to the action of heat by being passed over a flame s. The openings in the bottom of the holder permit the contacting surfaces that are to be soldered together to be exposed directly to the action of the heat, so that the solder is thoroughly melted. The can or receptacle may be retained in the holder until the solder is properly cooled and also maybe subjected to the action of a blower t, which facilitates and hastens the cooling process.

By means of this apparatus the parts to be soldered can be placed separately in the holder at different times and one part of the can or receptacle is firmly but yieldingly forced into contact with the other part while the solder is in a melt-ed condition, and the parts may be held rigidly in their proper re- .lation to each other until the solder sets.

Heretofore difficulty has been experienced in obtaining a tight joint, as the solder tends to accumulate in beads or drops around the edge of the body portion of the can or receptacle when same is dipped, which prevents the parts from contacting properly and causes the can or receptacle to leak. By firmly but yieldingly forcing the parts together while the solder is in a heated condition the beads or drops that tend to accumulate are broken up and the solder is distributed uniformly, lhus insuring a perfect joint.

I claim as my invention 1. An apparatus for soldering cans, comprising a holder having a bottom and rigid sides adapted to engage with the body portion of the can so as to firmly support the same, whereby the holder is adapted to receive separately the parts to be soldered and hold the same against movement with relation to each other, the holder being provided with means for yieldingly pressing said parts in engagement; substantially as described.

2. An apparatus for soldering cans, comprising a holder having a bottom and rigid sides corresponding with the body portion of the can so as to firmly support the same, whereby the holder is adapted to receive separately the parts to be soldered and hold the same against movement with relation to each other, the holder being provided with means for yieldingly pressing said parts in engagement; substantially as described.

3. An apparatus for soldering cans, comprising a holder having a bottom and rigid sides adapted to engage the body portion of the can so as to firmly support the same, whereby the holder is adapted to receive separately the parts to be soldered and hold the same against movement with relation to each other, the holder being provided with means for yieldingly pressing said parts in engagement, the bottom of the holder being provided with openings through which heat may be applied to the joint between the body portion and end of the can; substantially as described.

at. An apparatus for soldering cans comprising a holder adapted to receive separately the parts to be soldered and to guide the same into proper relation to each other and means for yieldingly pressing said parts in engage= ment; substantially as described.

5. An apparatus for soldering cans, comprising a hold er, a bar hinged to the holder,

a cover movably secured upon the bar, and a spring between said bar and cover, substantially as described.

6. An apparatus for soldering cans, comprising a holder having openings in its bottom adjacent to its sides, a bar hinged to the holder and provided centrally with an inwardly-projecting stud, a cover movable upon said stud, a spring arranged between the cover and bar, projections upon said bar for guiding the cover, a catch for detachably holding said cover in its closed position, and a carrier for said holder, substantially as described.

7. In a can-soldering machine, the combination of a carrier adapted to conduct canbodies and having a frame corresponding in shape to the shape of the can-body, said frame being adapted to receive and support a canbody in contact with the top, and means for heating the parts to be joined, substantially as described.

8. In a can-soldering machine, the combination of a carrier consisting of an endless belt, means for moving said carrier, a frame carried by said carrier, said frame being of a shape corresponding with that of the canbody, said frame being adapted to receive a can-body and a top therefor and hold them in contact with each other in position for soldering, and means for heating the parts to be soldered as they are carried by said carrier, substantially as described.

In testimony whereof I sign this application, in the presence of two witnesses, this 2d day of November, 1900.

FRANCIS P. MCCOLL.
